Thyroid hormones are key regulators of several metabolic pathways, with effects throughout the human body. Disorders of the hypothalamus-hypophysis-thyroid axis has numerous health consequences and several different clinical manifestations, which can make the prompt diagnosis of thyroid disorders a challenge. Case-finding for subclinical thyroid dysfunctions is one response to this issue. The question of whether a patient diagnosed with subclinical disease needs pharmacological treatment is an ongoing educational and clinical debate, not least as impairment of thyroid function may impact other conditions, including cardiovascular disease, dyslipidemia, obesity, and cognitive decline. As a consequence, patients with thyroid dysfunction have complex needs, crossing many traditional medical specialties. Increasing the understanding of risk factors for thyroid disease and of the myriad effects of thyroid hormones on the human body is advantageous for most healthcare professionals, all of whom are catered for with these specialist activities.
Iodine is crucial for the maintenance of thyroid homeostasis, with both iodine excess and iodine deficiency potential causes of thyroid autoimmunity, hyper- and hypothyroidism. However, the importance of iodine sufficiency is often overlooked in clinical practice. This Digital Learning Journey aims to increase awareness of the importance of screening and diagnosing thyroid disorders in high-risk populations, such as those living in iodine-deficient areas. The impact of thyroid hormones (and their deficiency) on fertility, pregnancy and on lipid metabolism will also be covered, ultimately aiding healthcare professionals in improving cardiometabolic health for all patients and providing women affected by thyroid dysfunction with family planning guidance.
